chore: release 3.1.2

[rokt-releases]

Release 3.1.2

These files should have changed during the release, if they didn't then this is likely an issue and should be investigated:

• package.json
• CHANGELOG.md

Fixed

• Bound android kit upper version in expo config plugin (#332)

PR Summary

Low Risk
Release metadata only (version and changelog); no runtime or plugin code changes in this diff.

Overview
Release 3.1.2 bumps the published package version from 3.1.1 to 3.1.2 in package.json and VERSION, and updates CHANGELOG.md with a dated 3.1.2 section and compare links.

The release notes document one fix already merged elsewhere: an upper bound on Android kit versions in the Expo config plugin, so kit artifacts stay aligned with the pinned android-core range and avoid pulling incompatible kit releases.
